Overview

This lease space is located in a lower level and offers a flexible open box floor plan suitable for a tenant custom buildout or an open-concept office setup. The space is sized as a single unit but can be demised into two separate 1,012-square-foot spaces, which may be helpful for multiple uses or smaller tenancy requirements. A gross lease structure is available and includes utilities.

The property is positioned in downtown Dubuque in the C4, Downtown Commercial zoning district. It is described as having excellent visibility and foot traffic within the Main Street district, with nearby parking for visitors and staff. The listing also notes convenient access to Highways 61, 151, and 20, supporting straightforward regional connectivity.

For tenants seeking a downtown location with a configurable interior, this space supports both larger single-tenant occupancy and the option to split into two units. The inclusion of utilities under a gross lease may simplify operating costs for an operator establishing or expanding a downtown presence. Prospective users can review the existing open plan and determine how best to tailor the layout to their specific requirements.
